Stupidest idea ever? Possibly, probably not. Complete wank-balls out of this world proportions of ridiculosity? Abso-fucking-lutely.
Glasgow Rangers promoting GAA? Hell hasn't quite frozen over. The biggots haven't dismantled their incestuous lodges. What the fuck is going on? Recessions do strange things to people alright. What kind of sick inbred tradition could this be spawning?
(any more suggestions for brit clubnames?)
On the otherhand, a Champions League style gaelic competition would probably shit all over every other type of sport or entertainment in the world... ever. Make it so!
